# What is the volume of a gas?

3 min read

##### Asked by: Justin Alvarez

At constant temperature and pressure the volume of a gas is **directly proportional to the number of moles of gas**. Not so coincidentally if V is constant instead of P then P = n (RT/V) At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas.

## How do you find volume of a gas?

*The formula is gas volume produced in liters is equal to the number of moles of gas multiplied by 24 liters per mole.*

## What is volume of gas in physics?

A mole of gas has a volume of **24 m ^{3} or 24000 cm^{3} at room temperature**. This value is known as the molar volume of a gas.

## Does gas have a volume?

Gas is a state of matter that has no fixed shape and **no fixed volume**. Gases have a lower density than other states of matter, such as solids and liquids.

## What is volume of liquid?

If volume is the amount of 3-D space contained by a closed surface (e.g. the amount of space within a given cube, or cylinder, or any other 3-D shape), liquid volume is **a way to measure an amount of liquid by describing it how much 3-D space it occupies**.

## What’s the volume of a solid?

The volume of a solid is **the measure of how much space an object takes up**. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units 3 units 5 units = 30 cubic units.

## How do you find volume?

**Units of Measure**

- Volume = length x width x height.
- You only need to know one side to figure out the volume of a cube.
- The units of measure for volume are cubic units.
- Volume is in three-dimensions.
- You can multiply the sides in any order.
- Which side you call length, width, or height doesn’t matter.

## What is volume formula?

Basically, the volume is equal to the product of area and height of shape. **Volume = Base Area x Height**. For shapes having flat surfaces such as cube and cuboid, it is easy to find the volume.

## What is the volume of liquid and gas?

Three states of matter exist—solid, liquid, and gas. Solids have a definite shape and volume. **Liquids have a definite volume, but take the shape of the container.** **Gases have no definite shape or volume.**

## What is the volume of water?

Multiply length (L) by width (W) to get area (A). **Multiply area by height (H) to get volume (V)**. Multiply volume by 7.48 gallons per cubic foot to get capacity (C). Find the capacity in gallons of a horizontal circular tank that has a diameter of 8 ft and is 12 ft long.

## Is volume of gas and liquid the same?

2. **Liquids have definite volume; gases do not have definite volume**.

## Why gas has no definite volume?

**Due to the weak internuclear force of attraction, the gaseous particles have enough kinetic energy and they can move in any direction without any restrictions**. Hence, the gases do not have a fixed shape and fixed volume.
